Vertical navmesh?

I’m wondering if it’s possible to make the navmesh pick polygons facing the world X- direction, making it a vertical navmesh?

I’m thinking of having AI flying around in a 2d platformer way and it seems (?) to me making a navmesh handle navigation for AI flying about would be the most straight forward way to do it.


Apologies for the bump, but anyone know an answer for this? We’re in the same dilemma and we really don’t want to go back through our entire game and rotating everything 90o in order to use navmeshes.

As far as im aware 3d space navemesh does not exist.
Have you checked the video on how they made flying ai?

Its a cheat method but it worked. Search youtube for ue4 flying ai.
